Replacement & Compatibility FAQ
Q: Is the 6AV6648-0BC11-3AX0 still in production?
A: This model has been superseded by the 2nd-generation KTP400 Basic PN (6AV2123-2DB03-0AX0). However, original units remain available as new-old-stock (NOS) or refurbished. Contact us for current availability.
Q: Can I use this panel with an S7-1200 PLC?
A: Yes. The KTP400 Basic PN connects natively to S7-1200 via PROFINET. Configure the connection in TIA Portal using the integrated HMI wizard.
Q: What is the panel cutout size?
A: The required cutout is 152 × 102 mm. Verify your enclosure dimensions before ordering a replacement.
Q: Can I migrate my existing project to the 2nd-gen KTP400?
A: Yes. TIA Portal supports device replacement with automatic project migration. Minor adjustments to screen layouts may be required.
Q: Do you provide a certificate of origin or conformity?
A: Yes, available upon request for all units. Please specify at time of order.
Q: Is the 6AV6648-0AC11-3AX0 (PROFIBUS) interchangeable with this model?
A: Mechanically identical, but the communication interface differs (PROFIBUS DP vs. PROFINET). They are not electrically interchangeable without network infrastructure changes.
